Since indoor air flow is not as smooth as outdoors, the concentration of inhalable pollutants is usually easily detected by people when the concentration of inhalable pollutants exceeds the standard allowable concentration by a large amount. For example, formaldehyde during secondary decoration, or formaldehyde in newly added furniture in a certain room. Another example is a fire in the kitchen. It is difficult to detect in the bedroom until the smoke drifts into the room when the fire is very strong. The fire sensor found in.

In general, fire sensors in the prior art identify fires through images or infrared rays, but inhalable pollutants are already produced when a fire just breaks out or is about to break out.

Therefore, how to quickly, sensitively and accurately detect the concentration value of indoor inhalable pollutants is a technical problem that needs to be solved in this application.

The inventive concept of this application is:

When the inventor of the present application conducted research on the above problems, he found that there are several important key points to solve the above problems:

First, indoor air has poor fluidity, and the location of inhalable pollutants is generally random and cannot be reliably predicted. When the inhalable pollutants are far away from the sensor, the sensor will only detect the inhalable pollutants when the actual concentration of the inhalable pollutants is already high. can be detected. That is to say, the problem of inhalable pollutants that cannot be diffused quickly and evenly needs to be solved.

Second, the detection methods for different types of inhalable pollutants vary widely. How can they be detected in a unified manner?

Third, sensors are generally arranged in fixed positions and cannot follow the user. That is, how to solve the problem of flexibly arranging sensors with the user's location as the core detection point.

In response to the above problems, the inventor of the present application has carefully analyzed and compared and found that some desktop or vertical air conditioning equipment, such as air humidifiers and water-washed air conditioning fans, can effectively emit water mist or water vapor into the air. Absorbs dust in the air. Therefore, the inventor of the present application creatively discovered that by adding adsorbent into the air to adsorb inhalable pollutants, and then actively transporting the air with the adsorbent to the sensor by establishing a wind field, this can effectively solve the above-mentioned problem. one question. Moreover, the gasified adsorbent can absorb a variety of inhalable pollutants, and the sensor can uniformly identify multiple pollutants by detecting changes in the adsorbent, thus solving the second problem. Secondly, desktop or vertical air-conditioning equipment can be flexibly transported. As long as the user arranges it in the space where it is located, it can not only regulate the air in the space, but also provide timely early warning of air quality. It kills two birds with one stone and solves the above-mentioned problem. Three questions.

The specific steps of the air abnormality early warning method provided by this application will be introduced in detail below with reference to several embodiments.

Figures 1a-1b are schematic diagrams of application scenarios of an air abnormality early warning method provided by this application. Figure 1a is a top view of the wind field in a certain space, and Figure 1b is a side view of the wind field in a certain space.

As shown in Figure 1a, there are two air conditioning devices in the space, namely air conditioning device 101 and air conditioning device 102. The flow diagram of their respective wind field fluids is shown in Figure 1a. Adsorbent liquid storage tanks can be added to the two air conditioning equipment. The blower of the air conditioning equipment blows air into the liquid storage tank to accelerate the evaporation or vaporization of the adsorbent, thus injecting the adsorbent into the wind field. The types of adsorbents in air conditioning equipment can be the same or different.

It should be noted that adsorbents include: water, alcohol, dry ice, nanoscale activated carbon, etc.

Similarly, as shown in Figure 1b, the desktop or vertical water-washed air conditioner 103 adds adsorbent to its water tank, so that the adsorbent evaporates or vaporizes with the water into the wind field.

The circulating wind field uses the air-conditioning equipment as the starting point of circulation, and returns the air that has absorbed inhalable pollutants to the sensors installed and detected inside the air-conditioning equipment. When the detected concentration of inhalable pollutants is greater than the preset threshold, an early warning message is issued to the user.

The specific air abnormality early warning methods are introduced below.

The air abnormality early warning method provided by this application can be set up in one or more air conditioning equipment. The air conditioning equipment includes: a controller, a blowing module and an adsorbent storage module. The controller stores information that can implement this application. The control program for the air abnormality early warning method provided.

Figure 2 is a schematic flow chart of an air abnormality early warning method provided by an embodiment of the present application. As shown in Figure 2, the specific steps of this air abnormality early warning method include:

S201. Send a wind field construction instruction to the blast module.

In this step, the wind field construction instruction is used to control the blowing module to construct a target wind field in the target space and add a gaseous adsorbent to the target wind field. The adsorbent is used to adsorb inhalable pollutants in the air.

In a possible implementation, the wind field construction instructions include: a wind speed instruction and a blowing direction instruction. The wind speed instruction is used to control the flow rate of the gas output by the blowing module, and the blowing direction is used to control the outlet of the blowing module. Wind direction to change the flow direction of fluids in the wind field.

It should be noted that the target wind field is a circulating wind field.

In a possible implementation, the gas in the circulating wind field circulates in a preset flow direction using the air blowing module as a circulation point, and the gas will eventually flow back into the air blowing module.

Specifically, the controller of the air conditioning equipment issues a wind field construction instruction to the blowing module. The blowing module adjusts the fan speed and the direction of the air outlet. For example, if the air outlet sweeps the air up and down or left and right, the fan speed will follow the flow of air from the air outlet. Different directions change the rotational speed, that is, the wind speed changes. The purpose of this is to make the wind field form a circulating wind field with the air conditioning equipment as the starting and ending point of the circulation.

The wind blown by the fan of the blower module can first pass through the liquid storage tank where the adsorbent is stored, thus accelerating the evaporation of the adsorbent.

Another possible implementation is to use an ultrasonic device to convert the liquid or solid adsorbent into a gaseous state, and the wind blown by the fan blows the gaseous adsorbent into the wind field.

S202. Obtain the concentration value of inhalable pollutants in the air.

In this step, the air contains an adsorbent.

Specifically, after the adsorbent absorbs inhalable pollutants, it returns to the air conditioning device along with the circulating wind field. One or more sensors are installed at the air suction inlet of the air conditioning device to identify a variety of different pollutants. Inhalable pollutants.

When the adsorbent carrying inhalable pollutants touches the sensor, the sensor can detect its concentration value.

In one possible design, the adsorbent chemically reacts with the inhalable pollutant, causing the invisible inhalable pollutant to become a visible gas, or mist, so that the sensor can use its visibility to collect images or mist. The principle of laser scattering is used to identify the concentration of respirable pollutants.

S203. If the concentration value meets the preset conditions, send an early warning message.

In this step, when the concentration of inhalable pollutants is greater than the preset threshold, the user is notified through APP, voice or beep, display panel, etc. At this time, abnormal air quality may occur, and the user is notified to check whether the surrounding environment is safe. Hazards, such as whether there is a fire hazard.

In one possible design, in order to prevent the sensor from fluctuations due to unknown reasons, such as temperature drift, it is necessary to continuously detect that m concentration values are greater than the preset threshold before the warning message is generated.

It should be noted that, as for the specific value of m, those skilled in the art can choose it according to the actual situation, and this application does not limit it.

The air abnormality early warning method provided by this embodiment sends a wind field construction instruction to the blowing module. The wind field construction instruction is used to control the blowing module to build a target wind field in the target space and add gaseous wind field to the target wind field. Adsorbent, the adsorbent is used to adsorb inhalable pollutants in the air, and then obtain the concentration value of the inhalable pollutants in the air, and the air contains the adsorbent. If the concentration value meets the preset conditions, an early warning message is sent. It solves the technical problem of how to accurately and sensitively detect abnormalities in indoor air quality. The combination of the diffusion effect of the wind field and the adsorption effect of the adsorbent achieves the technical effect of improving detection sensitivity and accuracy.

In order to specifically describe the detection method in S202, a specific embodiment will be introduced in detail below.

Figure 3 is a schematic flowchart of another air abnormality early warning method provided by an embodiment of the present application. As shown in Figure 3, the specific steps of this air abnormality early warning method include:

S301. Send a wind field construction instruction to the blast module.

In a possible implementation, the wind field construction instructions include: a wind speed instruction and a blowing direction instruction. The wind speed instruction is used to control the flow rate of the gas output by the blowing module, and the blowing direction is used to control the outlet of the blowing module. Wind direction to change the flow direction of fluids in the wind field.

It should be noted that the target wind field is a circulating wind field.

In a possible implementation, the gas in the circulating wind field circulates in a preset flow direction using the air blowing module as a circulation point, and the gas will eventually flow back into the air blowing module.

S302. During the preset sampling time, use the air quality sensor to obtain the concentration value of the preset number of inhalable pollutants in the air.

In this step, the adsorbent is contained in the air.

Specifically, within the preset total sampling time, for example, within 15 seconds, several sampling periods are set to collect a preset number of concentration values of inhalable pollutants. For example, 3 seconds is a sampling period to collect 5 inhalable pollutants. Pollutant concentration value.

It can be understood that those skilled in the art can select the total sampling time and sampling period according to actual conditions. And the total sampling time can be a combination of non-continuous times. For example, the total sampling time is divided into three sections, with each section separated by 30 seconds.

S303. Use the preset change rate model to determine the change rate of the concentration value based on the preset number of concentration values.

In this step, the change rate can be calculated according to formula (1), which is as follows:

Among them, ΔP _n represents the change rate of the concentration value, P _n represents the next concentration value, P _n-1 represents the previous concentration value, and t1 is the sampling period.

S304. If the change rate is greater than the first threshold, send early warning information.

In this step, when ΔP _n >P _limit , such as P _limit =1ug/(m3*s)), it is considered that the air quality is abnormal.

In one possible design, the air quality is considered abnormal only when the n consecutive change rates are greater than the first threshold. This can effectively avoid erroneous detection results caused by occasional numerical fluctuations of the sensor.

In this embodiment, sending early warning information includes:

Send an auditory alarm and/or a visual alarm to the user through a preset interface to notify the user to view the current environmental conditions of the target space.

Auditory alarms include: alarm bells, buzzers, voice alarms, etc.

Visual alerts include: LEDs lighting up or flashing, playing preset reminder videos, etc.

In a possible implementation, the air conditioning device can interact with other devices during the warning, such as smart speakers, smart displays, etc.

Furthermore, the user's location can also be identified through cameras or radar devices in the target space, and equipment near the user's location can be controlled to provide early warning.

In addition, after receiving the early warning information, the user can check the situation in the room through a smart camera, or smart infrared module, or an air conditioner integrated with a smart infrared module, and confirm whether there is a large amount of smoke or other harmful gases in the room for a short period of time, or whether Is there a possibility of fire?

S305. Obtain the feedback information input by the user and send the rescue information to the preset processing center.

In this step, the rescue information includes location information of the target space.

Specifically, when the user confirms that the abnormal situation in the room is a fire, the user can manually select the alarm in the APP application, and the air conditioning device can send the location information of the room to the alarm information platform of the local fire department to facilitate the fire department to accurately position.
